The book Im searching for is about a policeman/detective who is trying to uncover a conspiracy regarding the rich who harvest the souls of the dying. The dying sign up for a program that lets them calmly die in a dreamlike state. The program actually harvests their souls for the rich around the world to use to enhance themselves. It has dead people and undead people. Maybe even vampires. The detective dies and is re-animated by his dead lover. I know it sounds weird but it wasn't a dream it does exist. I belive its from a U.K. author.
